- the organic solvent is selected to have sufficient volatility to evaporate essentially entirely from the coating composition during the curing process such as during heating from 175-205 Q C. for about 5 to 15 minutes.
- suitable organic solvents are aliphatic hydrocarbons such as mineral spirits and high flash point VM&P naphtha; aromatic hydrocarbons such as benzene, toluene, xylene and solvent naphtha 100, 150, 200 and the like; alcohols, for example, ethanol, n- propanol, isopropanol, n-butanol and the like; ketones such as acetone, cyclohexanone, methylisobutyl ketone and the like; esters such as ethyl acetate, butyl acetate, and the like; glycols such as butyl glycol, glycol ethers such as methoxypropanol and ethylene glycol monomethyl ether and ethylene glycol monobutyl ether and the like.
- aliphatic hydrocarbons such as mineral spirits and high flash point VM&P naphtha
- aromatic hydrocarbons such as benzene, toluene, xylene and solvent nap
- the resinous vehicle typically has acid groups, such as acid functional acrylic polymers, that are at least partially neutralized with an amine to assist in the dispersion or dissolution of the resinous vehicle in the aqueous medium.
- acid groups such as acid functional acrylic polymers
- the diluent is used in the coating compositions in amounts of about 20 to 80, such as 30 to 70 percent by weight based on total weight of the coating composition.
- Adjuvant resins such as polyether polyols and polyurethane polyols may be included in the coating compositions to maximize certain properties of the resultant coating.
- the adjuvant resin is used in amounts of up to 50, typically 2-50 percent by weight based on weight of resin solids of the coating composition.
- Another optional ingredient that is typically present in the coating composition is a catalyst to increase the rate of cure or crosslinking of the coating compositions.
- acid catalyst may be used and is typically present in amounts of about 0.05 to 5 percent by weight.
- Suitable catalyst are dodecyl benzene sulfonic acid, methane sulfonic acid, paratoluene sulfonic acid, dinonyl naphthalene disulfonic acid and phenyl phosphonic acid. It has been found that the amount of acid catalyst in the coating compositions of the invention is not as great as would normally be expected due to the presence of the reaction product of the phosphorus acid with the polyglycidyl ether of cyclohexane dimethanol. This reaction product is acidic and has been found to contribute to the cure of the coating
- a lubricant for example, a wax which facilitates manufacture of metal closures by imparting lubricity to the sheets of the coated metal substrate.
- Preferred lubricants include, for example, carnauba wax and polyethylene-type lubricants. If used, the lubricant is preferably present in the coating compositions of at least 0.1 percent by weight based on weight of resin solids in the coating composition.
- Another useful optional ingredient is a pigment such as titanium dioxide. If used, the pigment is present in the coating compositions in amounts no greater than 70 percent by weight, preferably no greater than 40 percent by weight based on total weight of solids in the coating composition.
- Surfactants can optionally be added to the coating composition to aid in flow and wetting of the substrate.
- suitable surfactants include, but are not limited to, nonyl phenol polyether and salts. If used, the surfactant is present in amounts of at least 0.01 percent and no greater than 10 percent based on weight of resin solids in the coating composition.
- compositions used in the practice of the invention are substantially free, may be essentially free and may be completely free of bisphenol A and derivatives or residues thereof, including bisphenol A (“BPA”) and bisphenol A diglycidyl ether (“BADGE”).
- BPA bisphenol A
- BADGE bisphenol A diglycidyl ether
- Such compositions are sometimes referred to as "BPA non intent" because BPA, including derivatives or residues thereof are not intentionally added but may be present in trace amounts because of unavoidable contamination from the environment.
- the compositions can also be substantially free and may be essentially free and may be completely free of Bisphenol F and derivatives or residues thereof, including bisphenol F and bisphenol F diglycidyl ether ("BPFG").
- compositions contain less than 1000 parts per million (ppm), "essentially free” means less than 100 ppm and “completely free” means less than 20 parts per billion (ppb) of any of the above mentioned compounds derivatives or residues thereof.
- the coating compositions of the present invention can be applied to containers of all sorts and are particularly well adapted for use on food and beverage cans (e.g., two-piece cans, three-piece cans, etc.). Besides food and beverage containers, the coating compositions can be applied to containers for aerosol applications such as deodorant and hair spray.
- Two-piece cans are manufactured by joining a can body
- the coatings of the present invention are suitable for use in food or beverage contact situations and may be used on the inside or outside of such cans. They are suitable for spray applied, liquid coatings, wash coatings, sheet coatings, over varnish coatings and side seam coatings.
- Spray coating includes the introduction of the coating
- composition into the inside or outside of a preformed packaging container.
- Typical preformed packaging containers suitable for spray coating include food cans, beer and beverage containers, and the like.
- the sprayed preformed container is then subjected to heat to remove the residual solvents and harden the coating.
- a coil coating is described as the coating, typically by a roll coating application, of a continuous coil composed of a metal (e.g., steel or aluminum). Once coated, the coating coil is subjected to a short thermal, ultraviolet, and/or electromagnetic curing cycle, for hardening (e.g., drying and curing) of the coating.
- Coil coatings provide coated metal (e.g., steel and/or aluminum) substrates that can be fabricated into formed articles, such as two- piece drawn food cans, three-piece food cans, food can ends, drawn and ironed cans, beverage can ends, and the like.
- a wash coating is commercially described as the coating of the exterior of two-piece drawn and ironed ("D&l") cans with a thin layer of protectant coating.
- the exterior of these D&l cans are "wash-coated” by passing preformed two-piece D&l cans under a curtain of a coating
- each can is passed through a thermal, ultraviolet, and/or
- electromagnetic curing oven to harden (e.g., dry and cure) the coating.
- the residence time of the coated can within the confines of the curing oven is typically from 1 minute to 5 minutes.
- the curing temperature within this oven will typically range from 150 Q C. to 220 Q C.
- a sheet coating is described as the coating of separate pieces of a variety of materials (e.g., steel or aluminum) that have been pre-cut into square or rectangular "sheets". Typical dimensions of these sheets are approximately one square meter. Once coated, each sheet is cured. Once hardened (e.g., dried and cured), the sheets of the coated substrate are collected and prepared for subsequent fabrication. Sheet coatings provide coated metal (e.g., steel or aluminum) substrate that can be successfully fabricated into formed articles, such as two-piece drawn food cans, three- piece food cans, food can ends, drawn and ironed cans, beverage can ends, and the like.
- coated metal e.g., steel or aluminum
- a side seam coating is described as the spray application of a liquid coating over the welded area of formed three-piece food cans.
- a rectangular piece of coated substrate is formed into a cylinder.
- the formation of the cylinder is rendered permanent due to the welding of each side of the rectangle via thermal welding.
- each can typically requires a layer of liquid coating, which protects the exposed "weld” from subsequent corrosion or other effects to the contained foodstuff.
- the liquid coatings that function in this role are termed "side seam stripes”.
- Typical side seam stripes are spray applied and cured quickly via residual heat from the welding operation in addition to a small thermal, ultraviolet, and/or electromagnetic oven.
- reaction product was prepared as generally described in
- Example A using 0.286 equivalents of phosphoric acid per equivalent of epoxy.
- Carboxylic acid group containing acrylic resin partially neutralized with amine and dispersed in water.
- a clear varnish was prepared as generally described in Example 1 but substituting bisphenol A diglycidyl ether of Example B for the 1 ,4- cyclohexane dimethanol diglycidyl ether of Example A.
- Example 3 (Comparative)
- a clear varnish was prepared as generally described in Example 1 but omitting the 1 ,4-cyclohexane dimethanol diglycidyl ether of Example A.
- Coated cans as described above were also immersed for 10 minutes at 180 Q F. (82 Q C.) in a 1 % Joy detergent solution.
- the coated cans were dried and tested for adhesion as described above. The results are as follows:
